Content access devices that use local audio translation for content presentation

ABSTRACT

A content access device uses local audio translation for content presentation. The content access device receives video and first audio data associated with a first language. The content access device uses translation software and/or other automated translation services to translate the first audio data to second audio data associated with a second language. The content access device synchronizes the video with the second audio data and outputs the video and the second audio data for presentation. The first audio data may be audio, text, and so on. The second audio data may be output as audio, text, and so on.

FIELD

The described embodiments relate generally to audio translation. More particularly, the present embodiments relate to content access devices that use local audio translation for content presentation.

BACKGROUND

Content provider systems typically provide one or more different types of content from one or more content sources to one or more different types of content access devices. For example, cable television content provider systems may broadcast television programs or movies to set top boxes, and may also provide on demand movies or other content upon request. By way of another example, streaming media providers may provide streaming video and/or audio upon request to a variety of different computing devices.

Content provider systems typically provide content that includes speech audio and/or text of a particular language. For example, a television program may be recorded with English speech audio. In some situations, the content provider system may make another language version of the program available, such as where the television program is simulcast in Spanish or French, or where the English speech audio is provided in a primary audio stream but Spanish or French speech audio for the television program is also provided with the television program in a secondary audio stream.

SUMMARY

The present disclosure relates to content access devices that use local audio translation for content presentation. A content access device may receive video and first audio data associated with a first language. The content access device may use translation software and/or other automated translation services to translate the first audio data to second audio data associated with a second language. The content access device may synchronize the video with the second audio data and output the video and the second audio data for presentation.

In various embodiments, a content access device includes a communication unit, a non-transitory storage medium that stores instructions, and a processor. The processor executes the instructions to receive video using the communication unit; buffer the video in the non-transitory storage medium; receive, using the communication unit, first audio of a first language corresponding to the video; convert the first audio to first text in the first language; translate the first text to second text in a second language; generate second audio from the second text; synchronize the second audio with the video; and output the second audio with the video from the buffer.

In some examples, the processor synchronizes the second audio with the video using time stamps associated with the video and the first audio. In a number of examples, the processor synchronizes the second audio with the video by using motion analysis of the video to determine a speaker. In various examples, the processor synchronizes the second audio with the video by using speech analysis of the first audio to distinguish between speakers. In some examples, generation of the second audio replicates an audio voice fingerprint from the first audio. In various examples, the processor translates the first text by transmitting the first text to a translation server using the communication unit. In a number of examples, the processor translates the first text using translation software.

In some embodiments, a content access device includes a communication unit, a non-transitory storage medium that stores instructions, and a processor. The processor executes the instructions to receive video using the communication unit; receive, using the communication unit, first audio data of a first language corresponding to the video; use translation software to translate the first audio data to second audio data of a second language; synchronize the second audio data with the video prior to outputting the video; and output the second audio data with the video.

In various examples, the processor receives the first audio data prior to the video. In some examples, the first audio data is closed captioning data.

In some examples, the processor outputs the second audio data as text on a display. In a number of implementations of such examples, the content access device includes the display. In various implementations of such examples, the display is incorporated into an electronic device and the processor outputs the text on the display by transmitting the text to the electronic device.

In various examples, the processor receives the first audio data and the video from separate sources.

In a number of embodiments, a content access device includes a communication unit, a non-transitory storage medium that stores instructions, and a processor. The processor executes the instructions to receive video using the communication unit; receive, using the communication unit, first audio data of a first language corresponding to the video; translate the first audio data to second audio data of a second language; estimate a time to delay presentation of the video to account for a translation time of the first audio data; delay presentation of the video for the time; and output the video with the second audio data.

In some examples, the processor selects the second language based on received user input. In a number of implementations of such examples, the received user input is stored.

In various examples, the processor selects the second language based on a location of the content access device. In some examples, the processor receives the video and the first audio data in a single stream. In a number of examples, the processor receives the video and the first audio data as separate streams.

DETAILED DESCRIPTION

Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.

The description that follows includes sample systems, methods, apparatuses, and computer program products that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein.

Much of the content provided by content provider systems may only be provided with speech audio and/or text (such as closed captioning) in the language or languages in which the content was recorded. This may limit the audience for the content. The language chosen may correspond to the primary language associated with the market served by the content provider system. In some situations, multi-language support may be provided. However, this is typically restricted to one or two languages that are the next most common associated with the market, such as in markets where English is the most common language followed by Spanish and/or French.

Content providers may wish to support a broader variety of languages. Not only might this enable content providers to comply with the suggestions and/or requirements of regulatory bodies, such as the Federal Communications Commission, the content provider might have a larger possible audience. The world does not communicate in just one language, or even a handful. There are approximately 6500 languages in the world. While not all may be commonly used, and many regions may be heavily associated with one or two primary languages, there are an increasing number of regions that are associated with an increasingly diverse set of languages. Primary support in English with secondary support in Spanish and/or French may fall short in regions that are associated with Russian, Argentinian, Chinese, Japanese, Greek, and so on.

Regardless, multi-language support comes at a cost. It may be expensive to record multiple language tracks for content. Further, as the number of supported languages increases, the hardware and/or software resources used to support those languages increases. For example, storage may be used to store data for those languages, network bandwidth may be used to transmit the data for those languages, and so on. Such multi-language support may increase the amount of storage and/or storage devices used by the content provider system, consume more network bandwidth, increase the cost of the system, slow system operation, introduce transmission delays, and so on.

The following disclosure relates to content access devices that use local audio translation for content presentation. A content access device may receive video and first audio data associated with a first language. The content access device may use translation software and/or other automated translation services to translate the first audio data to second audio data associated with a second language. The content access device may synchronize the video with the second audio data and output the video and the second audio data for presentation.

By way of illustration, rather than expending resources to create and translate multiple languages for content, one language audio and/or text corresponding to video (such as closed captioning data) may be transmitted to a content access device. That audio and/or text may be used by local content access device hardware (and/or a cloud based or similar service for the content access device) to translate the audio and/or text (such as by using translation software) and generate audio and/or text in the target language (such as using text-to-speech software). The audio and/or text in the target language may then be synchronized with the video for output. The local content access device hardware may buffer the video and/or audio and/or text to delay output until the synchronized video and/or audio and/or text can be rendered together, avoiding lag. Alternatively, the translated audio and/or text may be synchronized with the video for output as closed captioning text in the target language. This may conserve transmission bandwidth, reduce possible transmission delays, reduce network loads, conserve storage, eliminate redundant storage and/or transmission hardware, improve system efficiency, increase system responsiveness, decrease server loads, enable support for more languages than were previously possible, and so on. In some implementations, synchronization may be performed using time stamps in the video and the audio and/or text, by motion analysis to determine when people (and/or particular people) are speaking, and so on. In various implementations, the target language may be determined based on user preferences, estimated based on positional awareness, and so on.

In various examples, the content access device may buffer the video during translation. This may prevent and/or reduce lag between the video and the second audio data. For example, the content access device may buffer the video for a fixed time period before output (such as thirty seconds), may buffer the video until the translation is complete, may estimate a time period for translation and buffer the video for the estimated time period, and so on.

In some examples, the content access device may receive the first audio data along with the video. In other examples, the content access device may receive the first audio data separately from the video. By way of illustration, the content access device may receive the first audio data in advance of the video in order to begin translation before the video is received. The first audio data and the video may be received from the same or different sources.

In a number of examples, the first audio data may be audio associated with a first language, such as speech. In such an example, the first audio may be converted to first text using speech recognition software and/or other automated speech recognition services. The first text may then be translated to second text associated with a second language. The second text may then be used for synchronization and/or output (such as closed captioning), and/or may be converted to second audio that may then be used for synchronization and/or output. By way of illustration, text-to-speech software and/or other automated text-to-speech services may be used to convert the second text to the second audio. In some implementations, neural text-to-speech software or the like may be used to generate the second audio with natural speech inflections. In various implementations, the text-to-speech software may be configured based on one or more audio voice fingerprints and/or other voice characteristics of the first audio so that the second audio more closely resembles the original speaker. By way of illustration, the text-to-speech software may be configured to replicate the audio voice fingerprint of the original speaker.

In other examples, the first audio may be translated directly to second audio. For example, the translation software and/or other automated translation service may perform speech translation, which may translate speech of the first language directly to speech of the second language without the intermediate step of converting to text and translating the converted text.

In other examples, the first audio data may be first text associated with a first language, such as closed captioning data. The first text may be translated to second text associated with a second language, which may be used for synchronization and/or output (such as closed captioning), and/or may be converted to second audio that may then be used for synchronization and/or output.

In various examples, the content access device may synchronize the video and the second audio data using time stamps in and/or associated with the video, the first audio data, and/or the second audio data. In other examples, the content access device may synchronize the video and the second audio data by performing motion analysis on the video to determine when people (and/or particular people) are speaking. In still other examples, the content access device may synchronize the video and the second audio data by analyzing the video and performing speech analysis on the first audio data to determine when a particular person with a particular audio voice fingerprint and/or other voice characteristics is speaking and the speech that corresponds to that particular person.

In a number of examples, the language into which the content access device translates may be determined by a number of different factors. In some implementations, the content access device may be configured to translate into the language. In other implementations, the language may be configured based on one or more user preferences. In still other implementations, the content access device may select the language based on positional awareness (such as a global positioning system and/or other location data that may be correlated to a language associated with a current position in order to determine a “most likely” language into which to translate).

These and other embodiments are discussed below with reference to FIGS. 1-12. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting.

FIG. 1 depicts an example system 100 for local audio translation for content presentation. The system 100 may include one or more content access devices 101 that are operable to receive content from one or more content provider system devices 102 via one or more communication networks 103 and perform local audio translation for the content. The content access device 101 may be operable to output the content for presentation, whether via an output device included in the content access device 101 and/or via an associated presentation device 105 (such as an associated display, television, speaker, computing device, mobile computing device, and so on). The content access device 101 may be further operable to communicate with one or more service servers 104 via the network 103, such as to perform various functions associated with local audio translation.

The content access device 101 may receive video and first audio data associated with a first language. The content access device 101 may receive the video and the first audio data from the content provider system device 102 and/or another content source. The content access device 101 may use translation software and/or other automated translation services to translate the first audio data to second audio data associated with a second language. In some examples, this may involve first decrypting the first audio data. The content access device 101 may synchronize the video with the second audio data and output the video and the second audio data for presentation, such as via an input and/or output device 111 of the content access device 101, the associated presentation device 105, and so on.

By way of illustration, rather than expending resources to create and translate multiple languages for content, one language audio and/or text (such as closed captioning data) corresponding to video may be transmitted to the content access device 101. The content access device 101 may use the audio and/or text (and/or a cloud-based or similar service for content access device 101) to translate the audio and/or text (such as by using translation software) and generate audio and/or text in the target language (such as using text-to-speech software). The content access device 101 may then synchronize the audio and/or text in the target language with the video for output. The content access device 101 may buffer the video and/or audio and/or text to delay output until the synchronized video and/or audio and/or text can be rendered together, avoiding lag. Alternatively, content access device 101 may synchronize the translated audio and/or text with the video for output as closed captioning text in the target language. This may conserve transmission bandwidth of the network 103, reduce possible transmission delays, reduce network 103 loads, conserve storage, eliminate redundant storage and/or transmission hardware, improve system 100 efficiency, increase system 100 responsiveness, decrease loads of the content provider system device 102, enable support for more languages than were previously possible, and so on. In some implementations, the content access device 101 may perform synchronization using time stamps in the video and the audio and/or text, by motion analysis (such as on one or more frames of the video) to determine when people (and/or particular people) are speaking, by a combination of these techniques (such as where motion analytics of the video are used to detect lip movement and ensure that synchronization performed according to time stamps is accurate), and so on. In various implementations, the content access device 101 may determine the target language based on user preferences, estimated based on positional awareness, and so on.

In various examples, the content access device 101 may buffer the video during translation. This may prevent and/or reduce lag between the video and the second audio data. For example, the content access device 101 may buffer the video for a fixed time period before output (such as thirty seconds), may buffer the video until the translation is complete, may estimate a time period for translation and buffer the video for the estimated time period, and so on.

In some examples, the content access device 101 may receive the first audio data along with the video. In other examples, the content access device 101 may receive the first audio data separately from the video. By way of illustration, the content access device 101 may receive the first audio data in advance of the video in order to begin translation before the video is received. The content access device 101 may receive the first audio data and the video from the same or different sources, such as from the content provider system device 102 and/or one or more other content sources.

In a number of examples, the first audio data may be audio associated with a first language, such as speech. In such an example, the first audio data may be converted to first text using speech recognition software and/or other automated speech recognition services, such as by the content access device 101 and/or the service server 104 at the request of the content access device 101. The first text may then be translated to second text associated with a second language. The second text may then be used for synchronization and/or output (such as closed captioning), and/or may be converted to second audio that may then be used for synchronization and/or output. By way of illustration, text-to-speech software and/or other automated text-to-speech services may be used to convert the second text to the second audio. In some implementations, neural text-to-speech software or the like may be used to generate the second audio with natural speech inflections. In various implementations, the text-to-speech software may be configured based on one or more audio voice fingerprints and/or other voice characteristics of the first audio so that the second audio more closely resembles the original speaker. By way of illustration, the text-to-speech software may be configured to replicate the audio voice fingerprint of the original speaker.

In other examples, the first audio may be translated directly to second audio. For example, the translation software and/or other automated translation service (implemented by the content access device 101 and/or the service server 104) may perform speech translation, which may translate speech of the first language directly to speech of the second language without the intermediate step of converting to text and translating the converted text.

In other examples, the first audio data may be first text associated with a first language, such as closed captioning data. The first text may be translated to second text associated with a second language, which may be used for synchronization and/or output (such as closed captioning), and/or may be converted to second audio that may then be used for synchronization and/or output. Text may have the additional advantage of being able to be transmitted ahead of video, possibly reducing perceptible lags that might otherwise occur when the text is translated and/or converted to audio. Additionally, transmitting text may use less bandwidth than audio, which may further reduce transmission costs, bandwidth consumption, lag, and so on.

In various examples, the content access device 101 may synchronize the video and the second audio data using time stamps in and/or associated with the video, the first audio data, and/or the second audio data. In other examples, the content access device 101 may synchronize the video and the second audio data by performing motion analysis on the video to determine when people (and/or particular people) are speaking. In still other examples, the content access device 101 may synchronize the video and the second audio data by analyzing the video and performing speech analysis on the first audio data to determine when a particular person with a particular audio voice fingerprint and/or other voice characteristics is speaking and the speech that corresponds to that particular person.

In a number of examples, the language into which the content access device 101 translates may be determined by a number of different factors. In some implementations, the content access device 101 may be configured to translate into the language. In other implementations, the language may be configured based on one or more user preferences. The content access device 101 may store the user preferences in the storage medium 112, access preferences stored by the content provider system device 102, and so on. In still other implementations, the content access device 101 may select the language based on positional awareness (such as a global positioning system and/or other location data from a location component of the content access device 101 and/or another device that may be correlated to a language associated with a current position).

In various implementations, the content access device 101 may receive video using the communication unit 113; buffer the video in the buffer 120; receive, using the communication unit 113, first audio of a first language corresponding to the video; convert the first audio to first text in the first language; translate the first text to second text in a second language; generate second audio from the second text; synchronize the second audio with the video; and output the second audio with the video from the buffer 120.

In some examples, the content access device 101 may synchronize the second audio with the video using time stamps associated with the video and the first audio. In other examples, the content access device 101 may synchronize the second audio with the video by using motion analysis of the video to determine a speaker. In still other examples, the content access device 101 may synchronize the second audio with the video by using speech analysis of the first audio to distinguish between speakers.

In a number of examples, generation of the second audio replicates an audio voice fingerprint from the first audio. In some examples, the content access device 101 may use the translation software by transmitting the first text to a translation server using the communication unit. In other examples, the content access device 101 may execute the translation software.

In some implementations, the content access device 101 may receive video using the communication unit 113; receive, using the communication unit 113, first audio data of a first language corresponding to the video; use translation software to translate the first audio data to second audio data of a second language; synchronize the second audio data with the video prior to outputting the video; and output the second audio data with the video.

In various examples, the content access device 101 may receive the first audio data prior to the video. In a number of examples, the first audio data may be closed captioning data.

In some examples, the content access device 101 may output the second audio data as text on a display. In various embodiments of such examples, the content access device 101 may include the display. In other embodiments of such examples, the display may be incorporated into an electronic device and the content access device 101 may output the text on the display by transmitting the text to the electronic device.

In various examples, the content access device 101 may receive the first audio data and the video from separate sources.

In a number of implementations, the content access device 101 may receive video using the communication unit 113; receive, using the communication unit 113, first audio data of a first language corresponding to the video; translate the first audio data to second audio data of a second language; estimate a time to delay presentation of the video to account for a translation time of the first audio data; delay presentation of the video for the time; and output the video with the second audio data.

In various examples, the content access device 101 may select the second language based on received user input. In some implementations of such examples, the received user input may be stored.

In a number of examples, the content access device 101 may select the second language based on a location of the content access device. In various examples, the content access device 101 may receive the video and the first audio data in a single stream. In other examples, the content access device 101 may receive the video and the first audio data as separate streams.

The content access device 101 may be any kind of electronic device. Examples of such devices include, but are not limited to, one or more desktop computing devices, laptop computing devices, server computing devices, mobile computing devices, tablet computing devices, set top boxes, digital video recorders, televisions, displays, wearable devices, smart phones, digital media players, and so on. The content access device 101 may include one or more processors 110 and/or other processing units and/or controllers, one or more non-transitory storage media 112 (which may take the form of, but is not limited to, a magnetic storage medium; optical storage medium; magneto-optical storage medium; read only memory; random access memory; erasable programmable memory; flash memory; and so on), one or more communication units 113, one or more input and/or output devices 111 (such as one or more displays, speakers, printers, remote control device receivers, buttons, keyboards, track pads, force sensors, capacitive sensors, touch screens, computer mice, and so on), and/or other components. The processor 110 may execute instructions stored in the non-transitory storage medium 112 to perform various functions. Such functions may include receiving user input via the input and/or output device 111, requesting content from the content provider system device 102 using the communication unit 113, receiving content from the content provider system device 102 and/or other content sources using the communication unit 113, performing local audio translation (such as speech-to-text functions, text-to-speech functions, neural text-to-speech functions, text translation functions, speech translation functions, synchronization functions, video motion analysis, audio analysis, and so on), requesting and/or receiving services from the service server 104 via the communication unit 113 as part of performing local audio translation (such as speech-to-text functions, text-to-speech functions, neural text-to-speech functions, text translation functions, speech translation functions, synchronization functions, video motion analysis, audio analysis, and so on), outputting content for presentation via the input and/or output device 111 and/or the presentation device 105, buffering video and/or other content in a buffer 120 defined in the storage medium 112 and/or other buffer, and so on.

Similarly, the content provider system device 102 may be any kind of electronic device. The content provider system device 102 may include one or more processors 114, non-transitory storage media 115, communication units 116, and/or other components. The processor 114 may execute instructions stored in the non-transitory storage medium 115 to perform various functions. Such functions may include receiving requests for content, providing content, communicating with the content access device 101 using the communication unit 116, and so on.

Likewise, the service server 104 may be any kind of electronic device and/or devices configured in a cloud computing configuration and/or other arrangement. The service server 104 may include one or more processors 117, non-transitory storage media 118, communication units 119, and/or other components. The processor 117 may execute instructions stored in the non-transitory storage medium 118 to perform various functions. Such functions may include receiving requests for local audio translation functions (speech-to-text functions, text-to-speech functions, neural text-to-speech functions, text translation functions, speech translation functions, synchronization functions, video motion analysis, audio analysis, and so on), providing local audio translation functions (speech-to-text functions, text-to-speech functions, neural text-to-speech functions, text translation functions, speech translation functions, synchronization functions, video motion analysis, audio analysis, and so on), communicating with the content access device 101 using the communication unit 119, and so on.

Although the system 100 is illustrated and described as including particular components arranged in a particular configuration, it is understood that this is an example. In a number of implementations, various configurations of various components may be used without departing from the scope of the present disclosure.

For example, the system 100 is illustrated and described as including the service server 104. However, it is understood that this is an example. In various implementations, the system 100 may use the content access device 101 and/or another device to perform the functions attributed above to the service server 104. In such an implementation, the service server 104 may be omitted. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

By way of another example, the system 100 is illustrated and described as including the presentation device 105. However, it is understood that this is an example. In various implementations, the content access device 101 and/or another device may present content. In such an implementation, the presentation device 105 may be omitted. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

By way of yet another example, the system 100 is illustrated and described as synchronizing video with translated audio data. However, it is understood that this is an example. In various implementations, lag between unsynchronized video and translated audio data may be acceptable without synchronization, quicker presentation may outweigh perceptible lag between unsynchronized video and translated audio data, and so on. In such implementations, synchronization may be omitted. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

In yet another example, the system 100 is illustrated and described as either the content access device 101 or the service server 104 performing one or more local audio translation functions (speech-to-text functions, text-to-speech functions, neural text-to-speech functions, text translation functions, speech translation functions, synchronization functions, video motion analysis, audio analysis, and so on). However, it is understood that this is an example. In various implementations, a hybrid approach may be used, such as where some functions are performed by the content access device 101 while others are performed by the service server 104, the content access device 101 takes over some of these functions allocated to the service server 104 if response latency increases, the service server 104 is allocated some of these functions originally allocated to the content access device 101 when the content access device 101 becomes overloaded, the content access device 101 performs translation of a first set of commonly used words and/or phrases and the service server 104 performs translation of a second set of less commonly used words and/or phrases, the content access device 101 performs translation when translation is to a commonly used language and the service server 104 performs translation when translation is to one of a less commonly used language, and so on. Further, the content access device 101 may be operable to communicate with one or more devices on a local area network and/or other devices that are otherwise “local” to the content access device 101, as opposed to the service server 104 being “remote” to the content access device 101, and the content access device 101 may use such a local device or devices to perform various of the local audio translation functions allocated to the content access device 101 as opposed to requesting services accordingly from the service server 104. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

Additionally, the above techniques are illustrated and described with respect to video associated with audio or audio data. However, it is understood that this is an example. In various implementations, the content access device 101 may extract text associated with a graphic interface and/or other graphic, translate the extracted text, and generate a modified graphic interface and/or other graphic that includes the translated text. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

FIG. 2 depicts a flow chart illustrating a first example method 200 for local audio translation for content presentation. This method 200 may be performed by the system 100 of FIG. 1.

At operation 210, an electronic device (such as the content access device 101) may operate. At operation 220, the electronic device may receive video. The flow may proceed to operation 230 where the electronic device may buffer the video. The flow may then proceed to operation 240 where the electronic device may receive first audio of a first language.

At operation 250, the electronic device may use speech recognition software to convert the first audio to first text in the first language. At operation 260, the electronic device may use translation software to translate the first text to second text of a second language. At operation 270, the electronic device may use text-to-speech software to generate second audio from the second text. In some implementations, the text-to-speech software may be neural text-to-speech software that is configured to generate speech from text with natural inflections. In various implementations, the text-to-speech software may be configured to replicate an audio voice fingerprint from the first audio in order to make the generated audio sound more like the second audio was spoken by the same speaker as the first audio.

The flow may then proceed to operation 280 where the electronic device may synchronize the second audio with the video. The electronic device may synchronize the second audio data and the video using time stamps in and/or associated with the video, the first audio, and/or the second audio; by performing motion analysis on the video to determine when people (and/or particular people) are speaking; by analyzing the video and performing speech analysis on the first audio to determine when a particular person with a particular audio voice fingerprint and/or other voice characteristics is speaking and the speech that corresponds to that particular person; and so on.

At operation 290, the electronic device may output the second audio with the video from the buffer. The electronic device may output the second audio with the video for presentation, such as for rendering by the electronic device and/or an associated presentation device.

The flow may then return to operation 210 where the electronic device may continue to operate.

In various examples, this example method 200 may be implemented as a group of interrelated software modules or components that perform various functions discussed herein. These software modules or components may be executed within a cloud network and/or by one or more computing devices, such as the content access device 101 of FIG. 1.

Although the example method 200 is illustrated and described as including particular operations performed in a particular order, it is understood that this is an example. In various implementations, various orders of the same, similar, and/or different operations may be performed without departing from the scope of the present disclosure.

For example, the method 200 is illustrated and described as the electronic device separately receiving the video and then the first audio. However, it is understood that this is an example. In other implementations, the electronic device may receive the video after the first audio, together with the first audio, and so on. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

By way of another example, the method 200 is illustrated and described as converting the first audio to text, translating the first text to second text, and generating second audio from the second text. However, it is understood that this is an example. In other implementations, the first text may be received instead of the first audio, the second text may be output with the video instead of the second audio, the first audio may be directly translated to the second audio without any text conversion operations, and so on. Various configurations are possible and contemplated without departing from the scope of the present disclosure.

An electronic device may synchronize the translated audio 432 and/or audio data and the video 430 by performing motion analysis on the video to determine the portion 435 in the video 430 where the particular person 434 is speaking. Further, although FIG. 4 illustrates one track of translated audio 432 and/or audio data and one particular speaker, it is understood that this is an example. In some implementations, multiple tracks of translated audio and/or audio data may be synchronized to multiple speakers identified in the video 430. For example, separate of translated audio and/or audio data may be synchronized for a young woman speaker, an older woman speaker, a young man speaker, an old man speaker, and/or any other combination of speakers.

FIG. 5 depicts a third example 500 of video 530 synchronized with translated audio 532 and/or audio data. In this example, the translated audio 532 may correspond to speech by a particular person speaking at a portion 536 in the video 530. An electronic device may synchronize the translated audio 532 and/or audio data and the video 530 by speech analysis on the first audio to determine the portion 536 in the video 530 when the particular person with a particular audio voice fingerprint and/or other voice characteristics is speaking and that the speech corresponds to the translated audio 532. Further, although FIG. 5 illustrates one track of translated audio 532 and/or audio data and one particular speaker, it is understood that this is an example. In some implementations, multiple tracks of translated audio and/or audio data may be synchronized to multiple speakers identified in the video 530. For example, separate of translated audio and/or audio data may be synchronized for a young woman speaker, an older woman speaker, a young man speaker, an old man speaker, and/or any other combination of speakers.

In various implementations, various orders of the same, similar, and/or different operations may be performed without departing from the scope of the present disclosure.

For example, the method 600 is illustrated and described as communicating with multiple servers to convert the first audio to first text in the first language, translate the first text to second text, and generate second audio from the second text. However, it is understood that this is an example. In some implementations, the electronic device may communicate with fewer servers that perform the above operations and/or fewer operations. By way of illustration, the electronic device may transmit the first audio to a server that converts the first audio to first text, translates the first text to second text, generates second audio from the second text, and returns the second audio to the electronic device. Alternatively, the server may receive the first audio, translate the first audio directly to the second audio, and return the second audio to the electronic device. Various configurations are possible and contemplated without departing from the scope of the present disclosure.
